DETAILED DESCRIPTION

Examples and aspects are discussed below with reference to the FIGS.However, it should be understood that the detailed description givenwith respect to these FIGS is for explanatory purposes only, and not byway of limitation.

In FIG. 1A, reference numeral 10 refers generally to a computer systemin accordance with an embodiment of the invention. The computer system10 may be a portable computer system such as a laptop or notebookcomputer, tablet, a personal or desktop computer or even a mobile phone,personal digital assistant (PDA), consumer electronic device or thelike. In the example embodiment illustrated in FIG. 1A, the computersystem 10 may take the form of a laptop computer.

As illustrated in FIG. 1A, the computer system 10 may include aprocessor or central processing unit (CPU) 11 and a touchscreen 12 whichis connected to the processor 11 and includes a graphical display 14, asan output device, and a touch sensor 13, as an input device. Thegraphical display 14 may be overlaid with the touch sensor 13, inconventional fashion. However, it is also possible that the touch sensor13 may be separated from the graphical display 14. The touchscreen 12therefore may have input and output capabilities and may be coupled orcommunicatively linked to the processor 11.

The computer system 10 may also include memory 15 communicativelycoupled to the processor 11. The memory 15 may be any suitable computerreadable storage medium (or media) which is configured to store programinstructions. The computer system 10 may also include the followingcomputer input devices which operatively may be connected to theprocessor 11 and are known in the art of laptop computers: a keyboard16, a video camera 17, a sound recorder or microphone 18, and a pointingdevice or mouse 19. Furthermore, the computer system 10 may include aprimary display 20 which may take the form of a Liquid Crystal Display(LCD) screen, Light Emitting Diode (LED) screen or other known displaysavailable on the market. The processor 11 is connected to the primarydisplay 20 in order to output graphics to the primary display 20.

During operation, the user may select and activate various userinterface objects in order to initiate functions or tasks associatedwith the objects. The computer system 10 and associated method describedbelow may significantly improve the efficiency and productivity of theuser by presenting the user with useful shortcuts or user interfaceobjects on the touchscreen 12, at appropriate times.

The computer system 10 may include the following core or primary modulesstored in the memory 15 which will be discussed in more detail below: auser context determination module 24, a user interface object predictionmodel 36, an icon selection module 26, and an icon display module 25. Asillustrated in FIG. 1B, the user context determination module 24 mayinclude the following submodules: a calendar module 22, an imageprocessing module 28, an audio processing module 30, a locationdetermination module 32, a time keeping module 34, a historical behaviormodule 23, an operating system interface module 27 and a force touchmodule 29.

Reference is now made to FIGS. 2 to 6 which illustrate various aspectsof a computer-implemented method of controlling the computer system 10in accordance with an embodiment of the invention. In FIG. 2, referencenumeral 40 refers generally to a method of controlling the computersystem 10 in order to display contextually relevant user interfaceobjects to a user on the graphical display 14 based upon a context ofthe user as determined by the user context determination module 24. Inbroad terms, the method 40 of controlling the computer system 10 mayinclude determining, at block 42, the user's context using the usercontext determination module 24, predicting 43, using the user interfaceobject prediction model 36, a probability of the user interacting withany one or more of a number of available user interface objects,selecting, at block 44, using the icon selection module 26, one or morecontextually relevant user interface objects based upon the user'scontext as determined by the user context determination module 24,determining, at block 45, a layout and size of selected user interfaceobjects using the icon display module 25 and displaying, at block 46,the contextually relevant user interface objects on the graphicaldisplay 14 of the touchscreen 12.

User interface objects are graphical images displayed as part of agraphical user interface on the graphical display 14 or primary display20 and may be represented as shortcuts, windows, fields, dialog boxes,menus, icons, virtual buttons, keys, cursors or scroll bars etc.

The method may include extracting user interface objects from agraphical user interface of an application currently running on thecomputer system 10. For example, shortcuts such as “Bold”, “Left Align”,“Font Size”, and “Font Color” may be captured or extracted from thegraphical user interface of a word processing application.

The icon display module 25 may determine the layout and size of iconsdisplayed on the touchscreen 12. Icons with a higher probability, asdetermined by the user interface object prediction model 36, may beassigned a more prominent position, and may be larger in size. Iconswith a lower probability may be assigned a less prominent position, andmay be smaller in size. The icon display module 25 may group togethericons with similar functionality, for example, icons concerning textformatting may be grouped together.

A variety of user context determination methods are contemplated withinthe scope of the illustrative embodiments. The user's context may bedetermined by a number of factors which include the user's age, acurrent location of the computer system 10 as determined by the locationdetermination module 32, a time of day as determined by the time keepingmodule 34, the user's behavior and mood or cognitive state of mind whichmay be determined by observing the user using any one or more of thevarious computer input devices including the video camera 17, soundrecorder 18, touch sensor 13, and keyboard 16. The user's context mayalso be determined by having regard to the user's schedule as determinedby the calendar module 22. Furthermore, it may be determined by havingregard to the application that the user is currently interacting with,and the user's actual activity within the application as determined bythe operating system interface module 27. For example, the user may bedrawing, writing, calculating or composing music/video. User context mayalso be based upon previous applications that the user has recentlyinteracted with, which may still be running in the background, or mayhave been closed by the user. The user context determination module 24may also make use of sensed ambient light conditions to determine theuser context.

The user context may be determined by monitoring, using the operatingsystem interface module 27, a user's interaction or engagement with thecomputer system 10 based upon actions performed by the user. Userinteractions may include event streams such as user's typing, scrolling,clicking, etc. The user interactions with the current application may beused to determine the current user activity (e.g. reading, writing,drawing, calculating, music/video composing etcetera).

FIGS. 3A and 3B illustrate a more detailed method 50 of controlling thecomputer system 10 in order to display contextually relevant userinterface objects on the touchscreen 12. For example, the method 50 mayinclude monitoring, at block 52, the user's behavior using the videocamera 17 and/or sound recorder 18 by capturing, at block 54,video/audio footage of the user. Once the footage has been captured itis forwarded to the processor 11 where image and/or audio processing isperformed, at block 56, by the image/audio processing modules 28, 30.

The method 50 may further include establishing a mood or cognitive stateof the user, at block 58, based on the outcome of the image/audioprocessing. For example, if the user makes a loud utterance or frowns,the computer system 10 may establish that the user is frustrated with apresent application and select, at block 60, using the icon selectionmodule 26, and display, at block 62, an “Undo” shortcut 9 or “Exit” icon7 on the graphical display 14 based on the user's cognitive state.Similarly, a “Save” icon 6 may be displayed if the image processingmodule 28 establishes that the user is drowsy. Alternatively, if theimage processing module 28 establishes that the user is happy, iconspertaining to the user's current activity may be displayed, for example,editing a word document.

Furthermore, based on the user's age, which may be determined by theuser context determination module 24 or which may be saved under a userprofile upon creation of the profile or otherwise derived, the computersystem 10 may be configured to select, using the icon selection module26, an age-appropriate icon or user interface object to display on thegraphical display 14. For example, an “Email” shortcut may be presentedif the user is an adult and a “Games” shortcut may be presented ordisplayed if the user is a minor.

Also, user context may be location-based. In other words, based upon apresent location of the computer system 10 as determined by the locationdetermination module 32, one or more user interface objects frequentlyused at the determined location or otherwise connected to the locationmay be displayed on the graphical display 14. For example, if the useris at work, the “Email” icon may be displayed but if the user is athome, an internet browser shortcut or other entertainment-relatedshortcut may be displayed.

Similarly, user context may be determined by the user contextdetermination module 24 based upon a time of day, as communicated by thetime keeping module 34. Accordingly, the method may include selecting44, using the icon selection module 26, contextually relevant shortcutsto display. For example, in the morning, a work-related applicationshortcut may be displayed on the graphical display 14 and in the eveninga shortcut related to leisure may be displayed.

User context may also be determined by the user context determinationmodule 24 having regard to scheduling of the calendar module 22. Forexample, if the user has a meeting scheduled in his calendar and iscurrently busy with leisure such as watching a movie, the icon displaymodule 25 may offer a “Fast Forward” or “Pause” icon on the graphicaldisplay 14. The selection 44 of relevant user interface objects by theicon selection module 26, to display on the graphical display 14 maydepend upon calendar events. In other words, a calendar event remindermay be displayed on the display 14.

In addition, user context may be determined by having regard to ambientlight intensity as sensed by the video camera 17 or by a separatededicated ambient light sensor of the computer system 10. Accordingly,the icon selection module 26 may select to display an icon or scroll barto adjust the brightness of the primary display 20 in the event that acurrent screen brightness is not suitable for the sensed ambient lightintensity.

FIG. 4 illustrates a method 70 for determining user context, andspecifically a user's mood or cognitive state based upon pressure sensedby the touch sensor 13. At block 72, the touch sensor 13 senses pressureapplied by the user during use of the touchscreen 12. The sensed forceor pressure applied may be compared, at block 74, to the user's historicinteraction with the touchscreen in order to ascertain, at block 76,whether or not the sensed pressure exceeds a predetermined threshold.Prior calibration may also be performed to identify a predeterminedthreshold or specify interactions with the touch sensor 13. If thepressure applied exceeds a maximum threshold or is below a minimumthreshold inferences, block 78, may be made with regards to the user'spresent mood or cognitive state. As before, appropriate user interfaceobjects may be selected, 44, and displayed, 46, based upon theinferences. For example, a light touch could indicate that the user istired and a “Shutdown” icon may be displayed. Alternatively, a hardtouch may indicate frustration and an “Exit” shortcut may be displayed.

FIG. 5 elaborates and provides more detail with regards to the methodillustrated in FIG. 2 and illustrates further steps 80 for determining auser's context and selecting contextually relevant user interfaceobjects which includes determining, at block 81, the user context usingthe plurality of context determination methods, capturing, at block 82,user interaction using any of the user input devices 16, 19, 13 as wellas keeping record 84, using the historical behavior module 23, of userinteraction with various user interface objects such as icons andshortcuts displayed on the displays 14, 20. The method further includestraining the user interface object prediction model 36 to compute theprobability of the user interacting with available user interfaceobjects. Training includes capturing or monitoring shortcuts selected bythe user in different scenarios. The user may choose shortcuts byclicking with the pointing device 19, or using the keyboard 16 to entera shortcut. The computer system 10 then uses an advanced machinelearning algorithm to build the user interface object prediction model36 which assigns a probability to each shortcut, given a particular setof inputs. The method may include ranking these shortcuts from highestprobability to lowest probability.

The user interface object prediction model 36 may be dynamic and changeas the user interacts with the computer system 10. For example, if anicon is displayed on the touchscreen, but the user doesn't make use ofit, then its probability decreases, and it is eventually removed fromthe graphical display of the touchscreen. If an icon is frequently used,then its probability increases, and consequently the icon may beassigned a more prominent position on the graphical display, and largersize. In another example of dynamic learning, the model 36 may identifya specific sequence of use of icons by a particular user, such asrepeated use of “Save”, “Close” and “Shutdown” icons in quicksuccession. Based upon this evaluation, the model 36 may be configuredto present the “Close” icon to the user upon the user selecting the“Save” icon in anticipation of the user's next engagement with thegraphical user interface. Similarly, upon the user selecting the “Close”icon, the “Shutdown” icon may be displayed automatically on thegraphical display 14. Alternatively the method may display a single iconwhich combines the commands “Save”, “Close”, and “Shutdown”.

Accordingly, regard may be had to an icon's ranking or probability whenselecting 44 contextually relevant user interface objects to display.Further method steps 90 are illustrated in FIG. 6 illustrative of use ofthe user interface object prediction model 36. These steps 90 includedetermining the user context 81 using the plurality of contextdetermination methods and assigning 92, using the user interface objectprediction model 36, a probability or rank to the available userinterface objects and determining 94, using the icon selection module26, which icons to display. The method further includes determining, atblock 95, using the icon display module 25, the layout and size of iconsto display on the graphical display and displaying 96 the icons on thegraphical display. The method involves choosing several icons orshortcuts with the highest probability to display on the touchscreen.

Furthermore, user profiling may be performed, by associating the userinterface object prediction model 36 with a particular user. The userinterface object prediction model 36 may be uploaded to a server in thecloud, whereby user interface object prediction models from differentusers may be aggregated together for a combined model.

In a further embodiment, the touchscreen may have three differentoperating modes namely static, cognitive and user-defined modes. Instatic mode, the touchscreen displays a predetermined list of shortcutsfor a particular application, i.e. application-driven display of userinterface objects. For example, when the user is browsing the internet,the touchscreen may display the shortcuts for “Forward”, “Backward”, and“Refresh”. In static mode, the touchscreen may always display the sameshortcuts for a particular application. Static mode may allow designersof software applications to determine which shortcuts they deem mostuseful for their applications. In contrast, in cognitive mode, the userinterface object prediction model 36 will determine which shortcuts todisplay. The shortcuts for a particular application may change dependingon the user's context, behavior, or cognitive state. In user-definedmode, the user is able to define rules for display.
